(a) Using a simple derivation or a simple argument to explain that the pressure at a point in a water tank is the same in all directions. (5 marks) (b) A 50 mm diameter syphon drawing oil of specific gravity 0.82 from a large reservoir, as shown in Figure Q5. Assume there is no head loss in the pipe Determine the mass flow rate of water from syphon, and also the pressure at point 2. Data given: Gravity acceleration 9.8 m/sĀ² Water density: 1,000 kg/mĀ³ The density of oil 0.82 Ć 1000 = 820 kg/mĀ³ (15 marks) Figure Q5

Step 1
The weight of the water is distributed equally in all directions, so the pressure is also distributed equally in all directions. b) To determine the mass flow rate of water from the syphon, we can use the Bernoulli's equation: P1 + 1/2Ļv1^2 + Ļgh1 = P2 + Show moreā¦

13. The two tanks A and B are connected using a manometer. If waste oil (density = 900 kg/m3) is poured into tank A to a depth of h = 0.6 m, determine the absolute pressure of the entrapped air in tank B. Air is also trapped in line CD as shown. Take water density = 1000 kg/m3.

Water flows from an open tank through an open outlet pipe as shown in the figure. (pwater = 1000 kg/m3) The height of point 1 is 12.0 m, and the height of points 2 and 3 in the outlet pipe is 4.0 m. The pressures at point 1 and point 3 are atmospheric pressure (101,000 Pa). The surface area of the reservoir is large enough that the velocity of the water at point 1 is negligible. The cross-sectional area of the outlet pipe at point 2 is A2 = 0.040 m2, and at point 3 is A3 = 0.020 m2.

Oil with a density of 890 kg/mĀ³ moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is Pā = 1.80 Ć 10ā“ Pa, and the pipe diameter is 5.00 cm. At another point y = 0.20 m higher, the pressure is Pā = 1.15 Ć 10ā“ Pa and the pipe diameter is 2.50 cm. (a) Find the speed of flow (in m/s) in the lower section. m/s (b) Find the speed of flow (in m/s) in the upper section. m/s (c) Find the volume flow rate (in mĀ³/s) through the pipe. mĀ³/s
